Can I require only "yes" to a yes or no question?
### Field Types

While you cannot directly require a "yes" response to a yes or no question, you could create a workaround following one of the below methods.

 - Use a [multiple choice question field](https://paperform.co/help/articles/how-do-i-add-multiple-choice-questions-to-my-form/) with one option ("yes.")
 - Use a [calculation field](https://paperform.co/help/articles/calculations-guide/) (selected plans only) to trigger an error if the desired option is not chosen.

The calculation field has a function called `ERROR("this is the provided error message.")`

 When it is called, the form cannot be submitted, and the provided error message will become visible to the end user.

Calculation example:

Calculation Example
Selecting the plus icon that appears on the right-hand side of the calculation input will allow you to select from your existing questions. This uses [answer piping](https://paperform.co/help/articles/what-is-answer-piping-and-how-do-i-set-it-up/) to display the submitter's response.

There are a few examples of preventing submissions in this [template](https://paperform.co/templates/prevent-submissions-template/).

## Gotchas

 - The calculation field must be visible to prevent the user from submitting the form.
